By almost any measure, gasoline is still cheap. In fact, it has probably been far too cheap for far too long. The recent price increases are only beginning to reflect its real value.

When measured on an inflation-adjusted basis, the current price of gasoline is only slightly higher than it was in 1922.

Gasoline is also a fairly minor expense when you consider the overall cost of car ownership. In 1975, gasoline made up 33.4 percent of the total cost of owning and operating a car. By 2006, according to the Bureau of Transportation Statistics, gasoline costs had declined to just 17.1 percent of the total cost of car ownership.
